We would like to get a warning when we receive a duplicate vendor invoice number

This feature is available on Payables Transactions Entry Screens as well as receiving transaction entry for "shipment/invoice" type but not just "shipment".

We realize that it is possible that one invoice may require more than one legitimate shipment/receipt and duplicate invoices need to be allowed.

We are just looking for a warning to let us know if it truly is a duplicate.

Thank you!
